To all whom t may concern;

Be it known that I, HENRY H. HUFF, of Boston, in the county of Snolk and State of Massachusetts,have invented certain ne w and useful Improvement-s in Track-SandingApparatus for Locomotives, of which the following is a speciiication.

This invention has for its object to provide simple and efficient means whereby sand can be supplied to the rails of a railroad-track by the use of compressed air, and also provide an apparatus in which the sand can be supplied interchangeably by compressed air or by gravity in the usual manner.

The invention consists in the improvements which I will now proceed to describe and claim.

Of the accompanying drawings, Figure 1 represents a side elevation of alocomotive embodying my invention. Fig. 2 represents a side elevation of a portion of the apparatus on a largerscale than that shown in Fig.;v 1. Fig. 3 represents a section on line 3 3 of Fig. 2 and a plan View of the parts below said line. Fig. 4 represents a section on line 4 4 of Fig. 2. Fig. 5 represents a view similar to Fig. 4, the horizontal blast-pipes being shown in plan instead of in section. Fig. 6 represents a section on line 6 6 of Fig. 3.

Fig. 9 represents a section on line 9 9 of Fig. 2. Fig. 10 represents an enlarged sectional view of one of the blast-pipes. Fig. 11 represents a section on line 1'1 11, Fig. 10. Fig. 12 represents a section on line 12 12 of Fig. 11. Fig. 13 represents a top plan View of a portion of the locomotive. Fig. 14 represents a section on-line 14 14 of Fig. 13. Fig. 15 represents a section on line l5 15 of Fig. 13.. Fig. 16 represents a section on line 16 16 of Fig. 13. Fig. 17 represents a side elevation of a portion of one of the sand discharge or delivery pipes. Fig. 18 represents a sectional view of the same. Figs.

19 and 2O represent sectional views showing features hereinafter referred to.

The same letters of reference indicate the same parts in all of the figures.

In the drawings, @represents the sand-box 5o of a locomotive, and b b sand-discharge pipes communicating therewith and arranged atopposite sides ofthe engine. Each pipe b comm unicates at its lower end with a casing c, having two blast-pipes d d extending horizontally through the casing. With the receiving endA of the pipes d d are connected air-supply pipes e @,which conduct compressed air from a suitable source of supply, the air passing through the blast-pipes d d, which are providedwith orifices CZ' d', communicating with the interior of the casing, so that a blast of air through either pipe induces a flow of sand from the casing c through the orifices d and the deliverypipes ff', connected with the outlet ends of the blast-pipes and extending to poi n ts in close proximity to the track-rail g, the pipefbeing in front of the forward drivin g-wheel and the through either of the blast-pipes, causing a supply of sand either in front of the front driving-wheel when the engine is moving forward and behind the rear driving-wheel when the engine is backing.

Each of the casings on the sides of the locomotive is adapted to receive sand from the sand-box, and the blast-pipes, located in each of said casings, are in practice embedded in the sand in said casing. The sand therefore flows readily into the blast-pipes through the orifices thereof and is ejected at the delivery end by the air supplied at the other end without the employment of an ejector-nozzle to eect such delivery. This arrangement also possesses the advantage of enabling the invention to be applied to a locomotive having the ordinary sand-box without alteration of the latter in any way, the casings and the pipe connections being readily applied to engines as now constructed.

In the casing, below the blast-pipes d d, is a valve or gate h, which retains the body of sand in the casing in position to be drawn through the orifices d' of the blast-pipe by the air-blast. From the lower portion of the casing c the outlet-pipe il extends to a point f by gravitation when the air-blast is not used.

with the plugj.

The valve 7i is provided with trunnions h' h', Fig. one of which is connected by the swiveljoint h2 and jointed rods h3 71:* with the cab of the locomotive, the arrangement being such that the engineer' can open or close the valve h by manipulating a handle h5 on the rod 7a4. 'lhe valve 7L in the casing at one side ot' the locomotive, is connected with the valve in the casing at the opposite side of the locomotive by means of arms h6 h6, attached to the `trunnions of the valves, and a rod 717,

= connectinrr the arms 71, as shown in Fig. 14

so that the two valves are opened and closed simultaneously.

Each ot' the blast-pipes d is provided with a device for varying the size of the sandoriiices fl and for distributing' the air-blast, said device comprising a plugj, which closely tits the interior of the blast-pipe and has a series of longitudinal oriiicesj, which subdivide the airblast and deliver it in numerous small jets in close proximity to the internal surfaces of the blast-pipe d at one end of the orifice Cl'. Said plug is provided with an extension jg, which is externally screwthreaded and engaged with an internal thread in one end of the blast-pipe and is provided with a square socket j; to receive a tool for turning the plugyl and its extension y2, and thereby adjusting the plug to causeit. to cover any desired part of the orice d', and thus varythe quantity of sand that will be drawn into the blast-pipe. The extension f has an orificej through which the air-blast enters two spaces or chambers .7'53'5 on opposite sides of the shankj, which connects the extension The air-blast or supplypipe e passes through the passagej'1 and into the chambers and through the orifices j.

The air-supply pipes e e may receive air from the source of supply which furnishes air to operate the brakes or from an independent source. In Fig. 16 I show one of the pipes e connected to a valve-casing k, having a valve 7c', adapted to be depressed by a lever k2, but the portion of the casing 7i; below the valve is connected with a pipe Z,

which communicates with the source of airvalvem is closed by the weight and prevents the entrance of moisture into the pipef.

The air-supply pipes e e are preferably branched at e e', Fig. 13, each pipe having page divisions, one of which supplies air to the 'casing c at one side of the engine, While the other supplies air to the casing at the opposite side of the engine.

In case damp sand should accumulate and be frozen inthe casing c and either of the delivery-pipes f, f', or i it may be removed by heating the air-blast and directing it into either of the said pipes by closing the others. The air may be heated by storing it by means of a suitable compressor in a reservoir so located as to be heated bya heated part of the engine. v

In Fig. 19 I show a partition o in the lower portion ot' the pipe b and in the upper portion oi` the casing c, said partition beine. between the blast-pipes d d. The object of the said partition is to equally divide the sand between the blast-pipes and prevent it from packing in the casing between the pipes.

In Fig. 20 I show the plugj affixed to an eXternallythreaded tubejs, which is engaged with an internal thread in the blast-pipe and is provided with a seatjf. jm is a ball which is pressed yieldingly by a spring f2 against t-he seat j. The ballj10 acts to distribute the blast uniformly between the orifices j. The shankji (shown in Figs. 4, 10, and 11) also acts as a. blast-distributer, causing the blast to uniformly enter the chamber-sf and oricesj.
